Description Matthew Mosesohn 2011-06-21 14:37:06 UTC

Description of problem:
If ipv6 is unavailable for your network, and the system has NETWORKING_IPV6=no marked in /etc/sysconfig/networking, SSSD still tries to use ipv6 automatically. SSSD should be intelligent enough to not try to use ipv6 if it's marked disabled.

Version-Release number of selected component (if applicable):
sssd-1.5.1-34.el6.x86_64

How reproducible:
intermittent

Steps to Reproduce:
1. set up SSSD
2. disable ipv6 via adding NETWORKING_IPV6=no to /etc/sysconfig/network
3. try to authenticate
  
Actual results:
timeouts occur because ipv6 is not enabled on the network

Expected results:
ipv6 dns requests should not occur

Additional info:
You can currently disable ipv6 for a service if you manually enter lookup_family_order=ipv4_only.

Thank you taking your time and submitting this request for Red Hat Enterprise Linux. Unfortunately, this bug was not given a priority and was deferred both in the upstream project and in Red Hat Enterprise Linux.

Given that we are unable to fulfill this request in following Red Hat Enterprise Linux releases, I am closing the Bugzilla as DEFERRED. To request that Red Hat re-considers the decision, please re-open the Bugzilla via appropriate support channels and provide additional business and/or technical details about its importance to you.

Note that you can still track this request or even contribute patches in the referred upstream Trac ticket.
